In this paper, we examine possible types of network formation among immigrants in the diaspora and between those … network structure on the country of origin, such as on international trade. We find that when the size of the diaspora is …

This paper reports results from a laboratory experiment on network formation among heterogeneous agents. The … experimental design extends the Bala-Goyal (2000) model of network formation with decay and two-way flow of benefits by allowing … private information. In all treatments, the (efficient) equilibrium network has a "star" structure. With homogeneous agents …

When workers send applications to vacancies they create a network. Frictions arise because workers typically do not … friction affects network formation, while the second coordination friction affects network clearing. We show that those … that can arise and the number of matches on a given network. Equilibria that exhibit wage dispersion are inefficient in …

We consider a model where each individual (or ethnic minority) is embedded in a network of relation-ships and decides … assimilation norms may emerge in steady state depending on the structure of the network. We then consider the role of cultural and …

We explore network effects on generosity for different network dimensions. To this end we elicit multiple network … matters for friendship ties but that structural network variables are important in all network dimensions. Importantly, these … effects are not invariant across different network dimensions. We also find that individual characteristics are unrelated with …

We develop and estimate a theory-consistent gravity model for interregional migration flows in the presence of … equation for bilateral mobility that embodies a co-determined local unemployment term. As a theory of migration, our model …

Can large-scale peer interaction foster entrepreneurship and innovation? We conducted an RCT involving almost 5 … submission of business plans and their quality, provided interaction displays some intermediate diversity. Network effects are …
